Bronchodilators relieve asthma symptoms by relaxing the muscle bands that tighten around the airways.
This action opens the airways, allowing more air come in and out of the lungs. Therefore, breathing improves.
Bronchodilators are most extensively used medications for treating asthma attacks brought on by physical activity or exercise [Exercise Induced Asthma].
Bronchodilators help in clearing the mucus from the lungs.
As the airways open, the mucus moves more freely and can be coughed out more easily. Theophylline is a bronchodilator used for asthma treatment, which relaxes the muscles surrounding the airways.
Bronchodilators are rescue medications and are used when needed and rarely on regular basis. These medications provide quick relief and relax the muscles of the airways. These are useful with exercise induced broncho-spasm and are usually in blue devices.
Bronchodilators for treating asthma:
- Beta 2 agonists
- Anticholinergic inhaler
Theophilline is another type of bronchodilator that is used for treating asthma. Brand names include theodur, uniphyll, phyllocontin and theolair. It is an oral medication which works directly to relax the airway muscles.
Theophylline is used at night time if shortness of breath disturbs sleep or more frequently if condition is severe. Side effects of this medication include rapid heartbeat, nervousness, loss of appetite, upset stomach, nausea, diarrhea, heartburn, muscle cramps, hyperactivity and headaches.

Side effects are warning of too much medication. Your doctor will check your blood levels to make sure you are receiving the proper amount. Inform your doctor when you are taking theophylline for treating asthma because certain medications can interfere with the way theophylline works.
Beta 2 agonists:
Beta 2 agonists that are used for treating asthma are salbutamol, fenoterol, terbutaline and pirbuterol. Beta 2 agonists are rescue medications which relax the muscles around the airways making breathing easier within minutes.
These are used when needed and rarely on regular basis. Short acting beta 2 agonists are also called quick acting or rescue medicines because they relieve the symptoms very quickly.
Beta 2 agonists are used to relieve symptoms of tightness in the chest, cough, wheezing and shortness of breath.
Overuse of short acting beta 2 agonists is a sign of unstable asthma. These medications work within 20 minutes and last four to six hours. Side effects of these medications include trembling, flushing, nervousness and increased heart rate.
Atrovent is an anticholinergic inhaler used for treating asthma. It opens the airways by blocking signals from the nervous system which cause the airways to become contracted. The maximum effect can be seen in one to two hours [Asthma Inhaler].
These are not used as an immediate emergency medication but can enhance the bronchodilator effect for certain asthma patients with difficult-to-control symptoms.
Dry throat is the common side effect. If medicine gets into your eyes, it might cause blurred vision for a short period of time.
Asthma medication could potentially save a life, so it is vital that chronic sufferers have it available to them at all times. Chronic patients can order the medicine that they need online, which is much more convenient than getting it from a pharmacy. The large quantities of medicine that many asthma sufferers require sometimes makes it difficult to keep track of, but receiving it on a set schedule removes all of the guesswork. This means that the medicine is delivered in intervals before it is needed, so that the patients never run out of these lifesaving products.
